[B_and_D]

I tested our front bed last week. I don't know about the rear bed. I've slept snugged up against the rear wall many times without the latch engaged (and never experienced a sinking feeling) but I haven't jumped up and down on it.

I tried rocking back and forth vigorously on the front bed, on my knees, with one knee on the very front of the front bed and the other more towards the center of the bed, and it started to tilt down a bit when I put my weight down on the knee right next to the front window. From this test, I'd say if someone who was fairly heavy wanted to sleep in the very front of the bed, or if you had some very rambunctious kids, you might want to be careful to engage the latches. I was surprised because we've never had this happen before.
